Application rues June 3, 1908. Serial No; 436.526.

To all whom it may concern:

Be it. known that I, Gsmn'r J. Roman, a

subject of the Queen of the Netherlands, residing at The Hague, Netherlands, have in- 1 5 vented certain new and useful Means in Telcphone Attachments, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to telephones and its.

bbjects are to provide a simple and inexpensive means whereby the customary electric circuitsnow used in connectionwith telephones may be used to set in operation with the telephone a talking machine and whereby the apparatus may be returned to normal condition ready for another operation upon the completion of themcssagedelivered by the tallnng machine to the tele hono I attain these objects by the device 1 lustrated in the accompanying drawings, in which similar characters of reference represent similar-parts throughoutthe various views, of which,

Figure 1 is a diagrammaticview. Fig. 2 is invention applied thereto, and Figs. 3 and 4 are rear and end views respectively of the the magnet 2 is energized. The armature 3 of said magnet is attracted arid the contact points 4 and 6 are closed by bridge 5. This closes the circuit of battery or other source of electric point 4, lea 7, magnet 9, lead 10, battery 100, leadll, branch 12, contact point 14, bridge 15, contact point 16, lead 17, magnet '18, lead 19, magnet 20, lead 21 and contact point 6. Magnets 9, 18, and 20 are energized from battery IOO'and the following results are accomplished: Illagn'et 9 attracts its armature 22 and by bridge 23 closes the contact points 24 and 26 so that through branch 27 and 28 the circuit of battery 100 is maintained when the signal circuit of the telephone is opened and the magnet 2 deenergized. Magnet 18 attracts its armature 29 thereby removing the brake. 30 from the talking machine. its armature 31 thereby lifting the telephone hook 32 or otherwise closing the sound circult of the telephone. T he talking machine has previously been made ready to seal: upon the brake 30 being lifted and can a firont view of a talking machine with my ower 100 as' follows: contact Magnet 20 also attracts I placed so that itshorn 33 will cooperate with the receiver (not shown) of the telephone. The talking machine will deliver its message to the telephone and when completed, the horn bearing arm 34 will come into contact with stop 36 attached by rod 37 to bridge 3% and move the same so that brid e 39 will close contact points 40 and 42. K new circuit is now made with battery 100 as follows: contact point 40, lead 41, magnet 42, lead 43, branch 12, lead 11, battery 100, lead 10, branch 44, contact point 42 and bridge 39. Another circuit is also made as follows 0on tact point 40, lead 41, branch 45, motor 46, branch 47, lead 11, battery 100 lead 10, branch 44, contact point 42 and bridge'39. Motor 46 being energized as above described will'operate worm 52 through belt 53 and pulley 54 and said worm 52' will through screw 55 return horn 33 to normal position, at which point arm 34 will strike stop 36 at contact ismaintained by bridge 15 between points 14 and 16 except when magnet 42 pulls said parts in the op osite direction so that when magnet 42 is eenergized by the break at bridge 39 spring 57 will make a break at bridge 15 thereby dcnergizing magnets 9, 18, and 20.

The arm 34 being fulcrumed at 56 the horn 33 will be moved into and out of operative position l movements of armature 48.

their respective parts to normal position.

2. The combination of a telephone and talking machine with means controlled by the signal circuit of the telephone whereby the sound circuitof the telephone is closed pulls through its armature 48 rod 49 the bar 50 over cam-surface 51,-or when spring 57 57-, 58 nd 59 are springs "for returning 61 are sup orts for the worm 52 and 62 rod 37 and thereby remove bridge 39 and break the circuit between points 40. and 42 I thus deenergizing motor 46.
